Key specifications

Selecting the right option

Confirm the NT40 (ISO40) taper on the arbor shank matches your machine's spindle socket. Select the JT (Jacobs Taper) size — #3 or #6 — that matches the bore taper of your drill chuck. The M16 × 2 draw bolt thread suits most NT40 machining centre spindles.
